WATER-CLOSET, 84,0.

SPECIFICATION forming part Of Letters Patent N0. 407,558, dated July 23,1889.

Application filed February 27, 1889. Serial No. 301,303. (No model.)

To all whom it may concern.-

Be it known that I, DARIUS WELLINGTON, a citizen of the United States,and aresident of Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inater-Closets and Similar Receptacles, of which the following, taken inconnection with the accompanying drawings, is a specification.

This invention relates. to water-closets and similar apparatus having avalved servicepipe leading from an elevated water-tank to theflushing-rim of the basin; and the objects of my invention are toprovide novel means for obtaining a noiseless flush of water, to providenovel means for ventilating the closet, and to otherwise improve thistype of apparatus, as will hereinafter appear.

The objects of my invention I accomplish in the manner and by thecombination of de vices hereinafter described and claimed, referencebeing made to the accompanying drawings, in which- Figure 1 represents aplan view of my invention. Fig. 2 represents a central longitudinalsection of my improved water-closet on the line A B, shown in Fig. 1,and also showing its connection to a supply-tank. Fig. 3 represents across-section of the closet on the line C D, shown in Fig. 2. Fig. 4represents a detail vertical section on the line E F, shown in Fig. 2 ofthe valve in the supply or service pipe; and Figs. 5, G, 7, and 8represent modifications of the same.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

(1 represents the basin of the water-closet having the trapped dischargeor outlet pipe to, the dip a" of which is below the level of the lowestpart a of the discharge-mouth of said trap. The basin a is provided witha flushing-rim a of any desired construction.

(t represents the inlet-opening for the flushing-water to said basin,and a represents the rear force-pipe, which enters the basin at a pointbelow the level'of the water in the trap of the basin, and preferably atthe lowest point of said trap.

Z) represents a, supply-tank, and b represents the supply or servicepipe leading from 0 represents a valve-casing interposed between thesupply-pipe b and the inlet-opening a and attached water-tight to saidinlet opening in any suitable manner, said casing having the opening 0coincident with the opening a 0 represents a valve-seat in the upperpart of the valve-casing c, which preferably projects a little downwardinto the valve-cas ing, and 0 represents a valve adapted to be seated onsaid valve-seat, either by means of a suitable float c, as shown inFigs. 2, 4, 5, 6, and '7, or by means of a spring 0 as shown in Fig. 8.

The valve-casing 0 extends below the opening 0, and forms a chamber forcontaining sufficient water to raise the float, and with it the valveagainst its seat.

I prefer to make the valve cup-shaped, as shown in Figs. 2, at, 5, and8, so as to contain a small quantity of water, and thereby to form aliquid seal to the mouth of the supply-pipe b when the valve 0 is heldagainst its seat, as described, and also to obviate the necessity of apacking, and to insure a joint between the valve and its seat, whichwill not allow air to enter the service or supply pipe when the valve ison its seat; but the valve may be made flat and supplied with a suitablepacking c", as shown in Fig. 6, or in the form of a ball 0 as shown inFig. 7, without departing from the spirit of my invention. When thevalve 1/ is raised, water flows through the supply-pipe b, and as theweight of the column of water in said pipe and supply-tank b is heavierthan the buoyancy of the float 0 the valve 0 will'be forced away fromits seat and allow the water to pass through openings 0 and a to flushthe basin, a portion of such water passing through the rear force-pipe ato help force the contents of the basin through the discharge-opening a.\Vhen the valve 1) is seated on the supply-pipe b and closes the same,the buoyancy of the float will force the cup-shaped valve immediatelyagainst its seat and prevent the water in the pipe I) from beingdischarged on account of the pressure of the air on the liquid in thecup-shaped valve being heavier than the column of water in the pipe Z).

(Z represents a ventilating-pipe leading to the open air at any suitableplace, said pipe being connected to a hollow chamber (1, in the lowerportion of the basin a, and (1 represents an opening from said chamber(1 into the discharge or soil pipe below the trap of the closet, and itwill be seen that any odor in the soil-pipe will pass through theopening CZ", chamber d, and ventilating-pipe (Z to the open air.

On account of the pipe (1 having free communication with the s0il-pipeand the open air, any suction in the soil-pipe tending to syphon on":the water in the seal of the closet will be relieved by air being drawnthrough pipe (I, chamber cl, and opening cl.

(1 in Fig. 2 represents a branch from the ventilating-pipe d, whichenters the valveeasin g 0 through the opening (Z in said valvecasingabove the normal level of the liquid in the valve-casing, and as anannular space 0 is left between the cup-shaped valve 0'' and its float 0free communication is established between the upper portion of the basina through the llushing'rim a", openings (0 c, valve-casing 0, pipe (1,and ventilating-pipe (Z to the open air, thus ventilating the upper partof the basin.

a represents an opening through the wall of the basin a, a little abovethe level of the water in the seal of the closet and communieating withthe rear force-pipe a, and through said force-pipe, openings a c,valve-casing c, branch pipe (1, and pipe (1 with the open air, thusfurnishing ventilation for the lower part of the basin a just above itsseal. 6 represents the base-plate on which the water-closet is adaptedto stand, and it is provided with a perforation e coincident with thedischargeopening in the closet. Said base-plate is preferably made ofmetal, and is secured to the floor by screws or other fastening devices,and the water-closet is fastened to the floor on said base-plate bymeans of the screws 6" e, which may also serve to fasten the base-plateto the floor, as shown in the drawings.

f represents a sleeve made of rubber or other suitable material, andprovided with a flange f in its upper end, fitting into acorrespondingly-formed recess in the lower part of the water-closet andclamped between the watercloset and base-plate c, as shown in Fig. 2,said sleeve f being adapted to enter the soilpipe and to make a tightjoint between it and the water-closet.

To the base-plate e is secured a bracket 6 as shown in Fig. 2, and tothe lateral horizont-al flange 4, formed at the top of said bracket, issecured the back board 9 of the seat of the water-closet, and to saidback board is hinged, by means of one portion of the spring-hinges g g,the seat g of the closet, said seat being provided with a cushion g,made of rubber or of other suitable material,whieh rests against theupper rim of the closet and forms an airtight joint between said closetand seat, pre venting any escape of odor from said closet at this place.

g represents the cover ot the closet, hinged to the seat by means of theother portion of the spring-hinges g g, and said cover isprovided withthe cushion g made of rubber or other suitable material, which makes anairtight joint between the seat and the cover, preventing all escapementof odor between the cover and seat; and it will be seen that all odor inthe closet must pass up through the flushing-rim w, or through theopening a and out into the open air through the ventilatingpipe (Z.

By securing the seat and cover to the baseplate by means of the bracket6 all strain in lifting the seat or cover to the closet is resisted bythe base-plate, and notby the 010. at, thereby preventing the liabilityof strain ng the joints in the closets, causing them. toleak.

The base-plate e is not an essential feature in this invention. as thebracket 6 and the water-closet may be screwed to the floor without suchbase-plate and the flanged sleeve f held between the lower part of thecloset and the upper end of the soil-pipe.

Having thus fully described the nature, construction, and operation ofmy invention, I wish to secure by Letters Patent, and claim- 1. Thecombination, with a water closet basin or similar receptacle having awaterinlet opening, a water-supply tank, a servicepipe for connectingthe tank with the inletopening, and a su pply-controllin g valve at theupper portion of the service-pipe, of a valveeasing inteposed betweenand communicating with the lower end of the service-pipe and theinlet-opening of the basin, and a self-closing valve located in saidvalve-easing between the lower end of the service-pipe and the basin,and automatically opened by the water-pressure when thesupply-controlling valve is opened to obtain a noiseless flush at alltimes, substantially as described.

2. Awater-closet basin or similar receptacle having opening a to admitwater to flush the basin, the tank Z), supply-pipe 12', valve 1) toclose the supply-pipe at the tank, valve-casing 0, having valve-seat c",and opening c, communicating with opening a in the basin,

valve c and float c to automatically open and close supply-pipe b at ornear the watercloset basin, all combined to be operated as described,for the purpose set forth.

3. In a water closet or similar receptacle, a basin provided with a itushing-rim and opening to admit water to flush the basin, a valve-casing communicating with the flushin g-openin g, a supply-pipe entering thevalve casin g, a valve to close the supply-pipe, and an airspace in theupper part of the valve-cas- ITO ing with the flushing-opening, and aventilating-pipe leading from the upper part of the valve-casing,combined with a passage-way in the wall of the water-closet, and anopening through the wall connecting the passageway with the basin of thecloset at or a little above the level of the Water in the seal of thecloset, to operate as ancl'for the purpose set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 23d (lay of February, A.D. 1889.

DARIUS WELLINGTON.
